IMPROVEMENT IN WATER-HEATERS.'

Specification forming part of Letters Patent No. 1 35,921, dated February 18, 1873.

To all 'whom yit may concern:

Be it known that I, JOHN KENFIELD, Jr., residing at Elmira, inthe county of Ohemung and State of New York, have invented a certai n' Improvement in Water-Heaters, of which the following is a'specitication: v

The nature of my invention consists in proriding a water-heater capable of use upon ordinary cooking stoves and ranges, and constructed with a series of vertical fines, con'- trolled by a suitable damper, to regula-te the extentot surface exposed to the hot air passing up into the smoke-pipe or chimney.

Figure l is a perspective view of my improved water-heater, the cap or hood being shown as suspended above it. Fig.` 2 is a vertical section, the cap being removed. Fig. 3 is aplan view ot' the damper.

The same letters of reference are used in all the Jgures in the designation of identical parts. f

The heater A, illustrated in the annexed drawing, is elliptical in form in horizontal seeton, and may be made of any required height. 'lhe water is introduced into it through the pipe ct, and delivered to different parts of a house through the pipe al. It is also provided with a cock, c2, for drawing Water from it directly. The heads of the heater are provided with a number of openings, b', upon each side ot' the central opening b, such openings being connected by tlnes B and B', respectively.v The openings 4in the lower head are controlled by a damper, O, so constructed and arranged that when it shuts Off all the flues B the central ue B will be Wide open, and also remain partially open when the iiues B are opened. The shell of the heater projects below the lower head, forming,1 a rim, with which the heater rests upon the top of the stove or range, leavin g sufficient space between the latter,l and the bottom of the heater for the accommodation of the damper C. An annular rim, A', is also formed upon the top of the heater around its flues to receive the cap or hood D, which conducts the waste heat to the smoke-pipe or chimney.

I prefer to make the central'and Outside iiues cylindrical inform, and the intermediate ones of the dat and curved form shown in Fig. l.

What I claim as my invention, and desire to-secure by Letters Patent, is

A water-heater containing lliues B and B,

in combination With the damper C and liood D, substantially as specified.

In testimony whereoflhave signed my name to this specification in the presence of two subscribing,` witnesses.
